Using javascript_include_tag with a Subfolder full of JS

I have a bunch of Javascripts in a folder under /public/javascripts/test and I want to include them in my layout using javascript_include_tag in as few lines as possible.

Currently I have 25 lines of code using javascript_include_tag, is there any way to do this better? Also I cannot use javascript_include_tag :all :recursive since there are some JS files in other directories that I do not want included.

Thanks for the help.

UPDATE: So now I have a javascript.rb initializer that has this single line of code (very long):

ActionView::Helpers::AssetTagHelper.register_javascript_expansion :syntax_highlight => Dir["#{Rails.root.to_s}/public/javascripts/sh/*.js"].each {|js| js.gsub!("#{Rails.root.to_s}/public/javascripts/",'')}

Now in my layout I have the follwing:

<%= javascript_include_tag :syntax_highlight %>

Now when I render the page I get the following:

<script src="/javascripts/sh/shAutoloader.js?1278089940" type="text/javascript"></script> 
<script src="/javascripts/sh/shBrushAppleScript.js?1278089940" type="text/javascript"></script>

<script src="/javascripts/sh/shLegacy.js?1278089940" type="text/javascript"></script> 

But for some reason none of this works? What gives?

Probably there's even better solution for that, but this will still do the trick:

Dir["#{Rails.root.to_s}/public/javascripts/test/*.js"].each {|js_file| javascript_include_tag js_file }

try this

In config/application.rb

uncomment this line

config.action_view.javascript_expansions[:defaults] = %w(javascript1.js javascript2.js)

and add the names of the files, like javascrip1.js and javascrip2t.js and so on.

Then in views/layouts add this line

<%= javascript_include_tag :defaults %>

Vlad Khomich's answer is also great and will work.

Considering that you are including so many js files, I am assuming, that you want to include all the js files under public directory. If this is the case, you can change in your javascript_include_tag as following, it will help you serve the whole file as one in production, saving lots of requests:

javascript_include_tag :all, :recursive => true, :cache => true

If you want to treat the test files saperately, you can register_javascript_expansion, like :defaults, and also use the code from Vlad Khomich's answer.

# config/init/javascript.rb
ActionView::Helpers::AssetTagHelper.register_javascript_expansion :tests => [array_of_js_paths_from_previous_answer]

# application.html.erb
<%= javascript_include_tag :tests, :cache => :tests %>
